Well, you can assume that audio is transported over dedicated
isochronous endpoints. The question is how audio parameters are set up.
And you can find out by tracing the traffic and see what happens when
you start or stop the stream, when you change the sample rate etc.

The only thing you can do as a customer and end-user is to pay attention
to the state of Linux support of a new piece of hardware before you buy.

Or waste some weekends and help yourself and maybe lots of others ;)
